Add Filter Expressions^WButton^WShortcut^WBookmark preferences.

Add comments noting that

- We might want to do something different when the bookmark button is
  pressed.
- The display filters (dfilters file) and gui.filter_expressions
  preferences should be merged.
- Many buttons on Qt4 + OS X + unifiedTitleAndToolBarOnMac makes the
  main window really wide.

Add a qstring_strdup convenience routine. Add "disabled" display filter
edit icons. Fix up whitespace and descriptions in a couple of places.
